DETAILED DESCRIPTION

[0023] The exemplary embodiments will be described in detail below with reference to the attached drawings. In the following description, the same numbers are used to denote the same elements, and a repeated description will be omitted. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0024] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed in compliance with the corresponding data protection regulations policy of the country where the device is located, and with the authorization given by the corresponding device owner.

[0025] As Figure 1 ​As shown, the present disclosure exemplarily provides an experimental device for air conditioner, which can be used for long-term running test of air conditioner. Specifically, the experimental device for air conditioner comprises an indoor unit room 1 and an outdoor unit room 2, the air conditioner comprises an air conditioner indoor unit 3 arranged in the indoor unit room 1 and an air conditioner outdoor unit 4 arranged in the outdoor unit room 2, the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 cooperate to cool or heat the indoor unit room 1. At least one of the indoor unit room 1 and the outdoor unit room 2 is provided with a heat exchange device, the heat exchange device comprises a fresh air mechanism 5 and an exhaust mechanism 6, the fresh air mechanism 5 is used for making the air of external environment into the indoor unit room 1 and the outdoor unit room 2, and the exhaust mechanism 6 is used for making the air in the indoor unit room 1 and the outdoor unit room 2 exhaust to the external environment.

[0026] The experimental device of the present disclosure can simultaneously perform long-term running test on the air conditioner indoor unit 3 and the air conditioner outdoor unit 4, so as to obtain the loss and other parameters of the parts of the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 under long-term running, and further improve the design. Specifically, the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 cooperate to heat the indoor unit room 1, and at the same time, the air conditioner outdoor unit 4 cools the outdoor unit room 2 to provide a low-temperature environment for the air conditioner outdoor unit 4 itself. Similarly, the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 cooperate to cool the indoor unit room 1, and at the same time, the air conditioner outdoor unit 4 heats the outdoor unit room 2 to provide a high-temperature environment for the air conditioner outdoor unit 4 itself. The indoor unit room 1 and the outdoor unit room 2 are closed structures, and the indoor unit room 1 and the outdoor unit room 2 can be provided with thermal insulation layers.

[0027] Different from the existing method of performing running test of air conditioner in open environment, the present disclosure places the air conditioner in a closed environment, which can realize variable-temperature long-term running of the air conditioner without being limited by the environment temperature. Such variable-temperature long-term running has low requirements for the selection of time nodes of the test, and is also beneficial to shorten the period of the test due to the long-time running. The test temperature can be provided by using a working condition machine or other air conditioning system to provide heat or cold, or can be achieved by heat exchange between the indoor unit room 1 and the outdoor unit room 2 as will be introduced later, which is not described here.

[0028] Considering that the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 may deviate from the target temperature range during the long-term running, specifically, as the heating process in the indoor unit room 1 continuously proceeds, the temperature in the indoor unit room 1 will be increased to above the target temperature range for a long time, and at the same time, the temperature in the outdoor unit room 2 will be gradually decreased to below the target temperature range for a long time, resulting in protective shutdown of the indoor unit room 1 and the air conditioner outdoor unit 4, and similarly, as the cooling process in the indoor unit room 1 continuously proceeds, the temperature in the indoor unit room 1 will be decreased to below the target temperature range for a long time, and at the same time, the temperature in the outdoor unit room 2 will be gradually increased to above the target temperature range for a long time, resulting in protective shutdown of the indoor unit room 1 and the air conditioner outdoor unit 4.

[0029] Based on this, as shown in the present disclosure, Figure 1As shown, the experimental equipment provided by the present disclosure is provided with heat exchange devices in at least one of the indoor chamber 1 and the outdoor chamber 2, and the heat exchange devices include a fresh air mechanism 5 and an exhaust mechanism 6. When the indoor chamber 1 or the outdoor chamber 2 deviates from the preset test temperature interval due to heat imbalance during long-term operation of the air conditioner, the air in the indoor chamber 1 or the outdoor chamber 2 is exhausted to the external environment by the exhaust mechanism 6, and at the same time, the fresh air of the external environment is introduced into the indoor chamber 1 or the outdoor chamber 2 by the fresh air mechanism 5. This part of the introduced fresh air can exchange heat with the air in the indoor chamber 1 or the outdoor chamber 2, so that the temperature returns to the test temperature interval, so as to ensure the reliability of the test results. In addition, the introduction of fresh air while exhausting part of the original air in the indoor chamber 1 or the outdoor chamber 2 is also beneficial to maintaining the air pressure balance.

[0030] The introduction of fresh air and the exhaust of original air can be achieved in various ways. For the introduction of fresh air, in some embodiments, the indoor chamber 1 or the outdoor chamber 2 is provided with a fresh air port 51 communicating with the external environment. The fresh air mechanism 5 includes an opening and closing device 52 for opening or closing the fresh air port 51. As shown in Figure 3 and Figure 4 The opening and closing device 52 can be configured to include a driving member 521 and a plurality of movable louvers 522, and the driving member 521 is used to drive the plurality of movable louvers 522 to rotate to open or close the fresh air port 51. This louver type opening and closing device 52 has the advantages of being able to control the air intake flow, responding quickly and avoiding foreign matter from entering. In addition, other types of opening and closing devices 52, such as the commonly used valve assembly controlled by a valve core to open and close, etc., as long as they can achieve the purpose of opening or closing the fresh air port 51, can be applied to the present disclosure.

[0031] For the exhaust of original air, in other embodiments, the indoor chamber 1 or the outdoor chamber 2 is provided with an exhaust port 61 communicating with the external environment, and the exhaust mechanism 6 includes a fan 62 arranged at the exhaust port 61. By controlling the rotation direction of the fan blade 62, the air in the indoor chamber 1 or the outdoor chamber 2 can be easily exhausted. The exhaust mechanism 6 can be provided with multiple ones, thereby improving the efficiency of heat exchange.

[0032] When it is necessary to exchange heat between the air in the indoor chamber 1 or the outdoor chamber 2 and the external environment, the opening and closing device 52 is controlled to open the fresh air port 51. Due to the action of the fan 62, the air in the indoor chamber 1 or the outdoor chamber 2 is exhausted to the external environment, and the indoor chamber 1 or the outdoor chamber 2 is in a negative pressure state. Under the action of the external atmospheric pressure, the air of the external environment can enter the indoor chamber 1 or the outdoor chamber 2 through the opened fresh air port 51.

[0033] In other embodiments, a fan 62 can also be provided at the fresh air inlet 51, when it is required to exchange heat between the air in the inner machine room 1 or the outer machine room 2 and the external environment, the rotating direction of the fan blade of the fan 62 is controlled to suck the air from the external environment into the inner machine room 1 or the outer machine room 2, and due to the increase of the internal air pressure, the original air in the inner machine room 1 or the outer machine room 2 can be discharged through the exhaust air outlet 61.

[0034] The relative positions of the fresh air inlet 51 and the exhaust air outlet 61 in the height direction can be set according to different experimental purposes and adaptability. Specifically, in some embodiments, as shown in Figure 2 The air conditioner is used to cool the inner machine room 1 or the outer machine room 2. Here, the cooling of the outer machine room 2 means that the air conditioner inner machine 3 and the air conditioner outer machine 4 cooperate to heat the inner machine room 1, and at the same time, the air conditioner outer machine 4 is cooled to provide a low-temperature environment for the air conditioner outer machine 4 itself. The heat exchange device is arranged in one of the inner machine room 1 and the outer machine room 2 for cooling, the fresh air inlet 51 is arranged adjacent to the top of the inner machine room 1 or the outer machine room 2, and the exhaust air outlet 61 is arranged adjacent to the bottom of the inner machine room 1 or the outer machine room 2. Considering that the low-temperature air deposits below the high-temperature air, the present disclosure arranges the fresh air inlet 51 adjacent to the top of the inner machine room 1 or the outer machine room 2, and arranges the exhaust air outlet 61 adjacent to the bottom of the inner machine room 1 or the outer machine room 2, which makes the low-temperature air below more easily discharged, and is beneficial to improve the efficiency of heat exchange.

[0035] In other embodiments, the air conditioner is used to heat the inner machine room 1 or the outer machine room 2. Here, the heating of the outer machine room 2 means that the air conditioner inner machine 3 and the air conditioner outer machine 4 cooperate to cool the inner machine room 1, and at the same time, the air conditioner outer machine 4 is heated to provide a high-temperature environment for the air conditioner outer machine 4 itself. The heat exchange device is arranged in one of the inner machine room 1 and the outer machine room 2 for heating, the fresh air inlet 51 is arranged adjacent to the bottom of the inner machine room 1 or the outer machine room 2, and the exhaust air outlet 61 is arranged adjacent to the top of the inner machine room 1 or the outer machine room 2. Considering that the high-temperature air floats above the low-temperature air, the present disclosure arranges the fresh air inlet 51 adjacent to the bottom of the inner machine room 1 or the outer machine room 2, and arranges the exhaust air outlet 61 adjacent to the top of the inner machine room 1 or the outer machine room 2, which makes the high-temperature air above more easily discharged, and is beneficial to improve the efficiency of heat exchange.

[0036] The inner machine room 1 can be provided with one, or can also be provided with two or more, and at least one outer machine room 2 is provided when one inner machine room 1 is provided. In some embodiments, as shown in Figure 1 The experimental equipment includes one inner machine room 1 and one outer machine room 2.

[0037] In other embodiments, as shown in Figure 2As shown, the experimental equipment includes an inner machine room 1, a first outer machine room 21 and a second outer machine room 22. The air conditioner inner machine 3 includes a first air conditioner inner machine 31 and a second air conditioner inner machine 32, and the air conditioner outer machine 4 includes a first air conditioner outer machine 41 arranged in the first outer machine room 21 and a second air conditioner outer machine 42 arranged in the second outer machine room 22, the first air conditioner inner machine 31 and the first air conditioner outer machine 41 cooperate to heat the inner machine room 1, and the second air conditioner inner machine 32 and the second air conditioner outer machine 42 cooperate to cool the inner machine room 1, wherein at least one of the inner machine room 1, the first outer machine room 21 and the second outer machine room 22 is provided with the heat exchange device described above.

[0038] The inner machine room 1 is used to accommodate the first air conditioner inner machine 31 and the second air conditioner inner machine 32 and simulate a normal temperature environment, for example, the target temperature interval of the normal temperature environment can be set to 23℃-28℃, the first outer machine room 21 is used to accommodate the first air conditioner outer machine 41 and simulate a low temperature environment, for example, the target temperature interval of the low temperature environment can be -16℃-1℃, and the second outer machine room 22 is used to accommodate the second air conditioner outer machine 42 and simulate a high temperature environment, for example, the target temperature interval of the high temperature environment can be 44℃-56℃. That is, the experimental system of the present disclosure can simultaneously perform long-term running test of the inner machine in the normal temperature environment and long-term running test of the outer machine in the extreme environment including the low temperature and the high temperature.

[0039] The first air conditioner inner machine 31 and the first air conditioner outer machine 41 cooperate to heat the inner machine room 1, and at the same time, the first air conditioner outer machine 41 cools the first outer machine room 21 to provide a low temperature environment for the first air conditioner outer machine 41 itself. Similarly, the second air conditioner inner machine 32 and the second air conditioner outer machine 42 cooperate to cool the inner machine room 1, and at the same time, the second air conditioner outer machine 42 heats the second outer machine room 22 to provide a high temperature environment for the second air conditioner outer machine 42 itself. The inner machine room 1 has both the heating first air conditioner inner machine 31 and the cooling second air conditioner inner machine 32 running at the same time, so that the inner machine room 1 can be in a normal temperature environment. By arranging the heat exchange device, when the inner machine room or the outer machine room deviates from the preset test temperature interval during the long-term running of the air conditioner, the temperature can be returned to the test temperature interval by introducing the external fresh air and discharging the original internal air, so as to ensure the reliability of the test results.

[0040] In addition, the temperature can also be adjusted by exchanging heat between the inner machine room 1 and the outer machine room 2, for example, by flowing the air in one of the inner machine room 1 and the outer machine room 2 into the other. Taking the embodiment in which the experimental equipment includes an inner machine room 1 and two outer machine rooms 2 as an example, the heat exchange device can be arranged between the inner machine room 1 and the outer machine room 2, and the heat exchange device can be arranged between the first outer machine room 21 and the second outer machine room 22. Figure 2The first air flow passage 71 is configured to allow air to flow from the second outer machine chamber 22 to the inner machine chamber 1, and the second air flow passage 72 is configured to allow air to flow from the inner machine chamber 1 to the second outer machine chamber 22. When the current temperature of the inner machine chamber 1 is lower than the lower limit of the target temperature range thereof, the temperature of the inner machine chamber 1 is increased to the first target temperature range by allowing the air with a higher temperature in the second outer machine chamber 22 to flow into the inner machine chamber 1, or when the current temperature of the second outer machine chamber 22 is higher than the upper limit of the first target temperature range thereof, the temperature of the second outer machine chamber 22 is decreased to the first target temperature range by allowing the air with a lower temperature in the inner machine chamber 1 to flow into the second outer machine chamber 22. The heat exchange processes between the inner machine chamber 1 and the first outer machine chamber 21 and between the first outer machine chamber 21 and the second outer machine chamber 22 are similar, and thus are not described herein again.

[0041] The heat transfer is performed between any two of the inner machine chamber 1, the first outer machine chamber 21 and the second outer machine chamber 22, the heat exchanged is generated during the operation of the inner machine and the outer machine, and the heat transfer occurs between the interiors of the machine chambers, so that the target temperature of each machine chamber can be maintained without the aid of an additional energy consumption device such as a working condition machine, which is beneficial to saving the consumption of electric energy, reducing the cost and being conducive to environmental protection and energy saving.

[0042] In some embodiments, the heat exchange device is arranged in the second outer machine chamber 22. When the temperature in the second outer machine chamber 22 is too high to be reduced by heat exchange with the air in the inner machine chamber 1 or the first outer machine chamber 21, or the temperature in the inner machine chamber 1 or the first outer machine chamber 21 has been stabilized in the test temperature range and does not need to be adjusted by heat exchange with the air in the second outer machine chamber 22, the air in the second outer machine chamber 22 can directly exchange heat with the external environment.

[0043] The second outer machine chamber 22 is provided with a fresh air inlet 51 and an exhaust air outlet 61 which communicate with the external environment, the fresh air inlet 51 is arranged adjacent to the bottom of the second outer machine chamber 22, and the exhaust air outlet 61 is arranged adjacent to the top of the second outer machine chamber 22. Considering that the high-temperature air is deposited above the low-temperature air, the fresh air inlet 51 is arranged adjacent to the bottom of the second outer machine chamber 22, and the exhaust air outlet 61 is arranged adjacent to the top of the second outer machine chamber 22, which makes the high-temperature air above more easily discharged, and is beneficial to improving the efficiency of heat exchange.

[0044] In addition, in some embodiments of the present disclosure, the experimental equipment can be provided with a refrigerant outlet for discharging the refrigerant leaked by the air conditioner. In this way, the refrigerant can be prevented from remaining in the inner machine chamber 1 or the first outer machine chamber 21 or the second outer machine chamber 22, thereby endangering the health of the test personnel. Moreover, considering that some commonly used refrigerants have the characteristics of being flammable and explosive, timely discharge is also beneficial to improving the safety performance of the experimental equipment.

[0045] In the detailed description above, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific aspects in which the disclosure can be practiced. In this regard, directional terminology, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and other commonly used terms, are used herein for the purpose of illustration only and are not intended to be limiting. Because the described devices can be positioned in a number of different orientations, the directional terminology can be used for illustration purposes only and is not limiting. It is to be understood that other aspects can be utilized and structural or logical changes can be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.

[0046] It is to be understood that the features of the various aspects of the disclosure described herein can be combined with each other, unless specifically noted otherwise. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items; similarly, "at least one of' includes any and all combinations of one or more of the associated listed items.

[0047] It should be understood that, unless otherwise specifically stated and limited, the terms "joined," "attached," "mounted," "connected," "fixed," and terms of similar meaning in the embodiments of the disclosure adopted herein should be construed in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection or communication with each other; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. The specific meaning of the above terms in this paper can be understood according to the specific circumstances by those skilled in the art.

[0048] In addition, the word "over" as used in reference to a component, element, or material layer being "over" another component, element, or material layer in the formation or location of a component, element, or material layer "over" a surface can be used herein to mean that the component, element, or material layer is positioned (e.g., placed, formed, deposited, etc.) "indirectly" on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the word "over" as used in reference to a component, element, or material layer being "over" another component, element, or material layer in the formation or location of a component, element, or material layer "over" a surface can also optionally have the specific meaning that the component, element, or material layer is positioned (e.g., placed, formed, deposited, etc.) "directly" on the surface, e.g., in direct contact with the surface.

[0049] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0051] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0052] Likewise, although the present disclosure has been described and illustrated with respect to one or more implementations, equivalent alterations and modifications will become apparent to those skilled in the art that do not depart from the true spirit and scope of the disclosure. The present disclosure includes all such modifications and alterations and is limited only by the scope of the following claims. In particular regard to the various functions performed by the above described components (e.g., elements, resources, etc.), the terms (including a reference to a "means") used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the described function (e.g., a functional equivalent), even though not structurally equivalent to the disclosed structure. In addition, although a particular feature of the disclosure can have been disclosed with respect to only one of several implementations, other implementations can include the particular feature. For example, the features of one implementation can be combined with those of another implementation. Furthermore, although the foregoing has been described in some detail for purposes of clarity, it will be apparent that certain changes and modifications can be made which will be readily apparent to those skilled in the art. It is intended to cover all such modifications and changes that fall within the scope of the disclosure, including full equivalents. In general, the terms used are intended to have their ordinary meanings in the art which can vary with context. It will be apparent that examples, illustrative implementations and embodiments described herein can be practiced by other than the methods and examples that are specifically described. Accordingly, this description is not intended to limit the scope of the disclosure, as claimed, but is merely contemplated to provide a reasonable disclosure of combinations and sub-combinations of the various features described and / or illustrated herein.
